Book excerpt: Excerpt from Engineering Descriptive Geometry: A Treatise on Descriptive Geometry as the Basis of Mechanical Drawing, Explaining Geometrically the Operations Customary in the Draughting Room The aim of this work is to make Descriptive Geometry an integral part of a course in Mechanical or Engineering Drawing. The older books on Descriptive Geometry are geometrical rather than descriptive. Their authors were interested in the subject as a branch of mathematics, not as a branch of drawing. Technical schools should aim to produce engineers rather than mathematicians, and the subject is here presented with the idea that it may fit naturally in a general course in Mechanical Drawing. It should follow that portion of mechanical Drawing called Line Drawing, whose aim is to teach the handling of the drawing instruments, and should precede courses specializing in the various branches of drawing, such as Mechanical, Structural, Architectural, and Topographical Drawing, or the "Laying Off" of ship lines. The various branches of drawing used in the different industries may be regarded as dialects of a common language. A drawing is but a written page conveying by the use of lines a mass of information about the geometrical shapes of objects impossible to describe in words without tedium and ambiguity. In a broad sense all these branches come under the general term Descriptive Geometry, It is more usual, however, tp speak of them as branches of Engineering Drawing, and that term may well be used as the broad label. The term Descriptive Geometry will be restricted, therefore, to the common geometrical basis or ground work on which the various industrial branches rest. This ground work of mathematical laws is unchanging and permanent. The branches of Engineering Drawing have each their own abbreviations, and special methods adapting there to their own particular fields, and these-conventional methods change from time to time, keeping pace with changing industrial methods. Descriptive Geometry, though unchanged in its principles, has recently undergone a complete change in point of view.
